Tonight's experimental-film program feels like an hour-long look into the wrong end of a telescope, as visual experiments hit the eye in dazzling and disorienting ways. Spanning 25 years, these music videos and shorts go beyond the mainstream's myopic preferences, and include the Cars' nightclub escapades in the Andy Warhol-directed "Hello Again," Laurie Anderson's playful polychromatic graphics in "Sharkey's Day," and Sonic Youth's stage-meets-special-effects tribute to Karen Carpenter, "Tunic (Song for Karen)." As the selections near the present day, the reliance on turn-of-the-20th-century tricks (superimposition, layering, and dissolves) transitions into sound-technology avant-gardism and a fascination with faux-verité footage.
